If the sun gives off a black body well, surface temp 4700 deg k, coincidence humans see light?

Answer 1

If I understand your question correctly...its not a coincidence that humans see the frequencies of light that the sun gives off a lot of. Our eyesight is the perfect example of evolution in action. Nature selects eyes that are efficient.

Answer 2

very large and focused solutions already given right here. i will function some extra strains to it. Aum corresponds to the 7 ranges in human understanding point a million. Jagrata or wakeful state - A of Aum point 2. Umnami - Transition to point 3 point 3. Swapnam - Antaratman - Semiconscious or a million/2 sleep - U of Aum point 4. Aladani - Transition to point 5 point 5. Sushupti - Paramatman - subconscious or Deep sleep) - M of Aum point 6. Samadhi point 7. AUM - all the states get merged and dissolved. it is the silence after AUM. The Turiyam - State of understanding In Rajayoga representation, this is slightly diverse: A - Sooryamandalam - Anaahatham and Manipoora. U - Somamandalam - Aajna and Visudhi Chakram. M - Vahnimandalam - Swaadhishtaanam and Moolaadhaaram. 'Aum is the imperishable syllable. Aum is the Universe, and it is the exposition of Aum. The previous, the present and the destiny, all that replaced into, all this is, all which would be, is Aum. Likewise all else that would exist previous the barriers of Time, that too is Aum. (Verse a million, Mandukya Upanishad of the Atharvaveda).

Answer 3

Umm, I'm not sure I completely understand your question, so I'll answer the question I think you're asking...

The Sun emits energy in all parts of the electromagnetic spectrum, but most of its energy is given off in the visible part of that spectrum. It is NOT a coincidence that humans see visible light - we evolved this way to take advantage of the majority of the light given off by the Sun. If our Sun were hotter, our eyes would have evolved to see light of shorter wavelengths, and if it were cooler - longer wavelengths.

Answer 4

Black body radiation is not radiation given off a black (invisible) object. Black body radiation refers to the phenomenon that hot objects in the temperature range of most average stars has a rather uniform light curve of frequency.
We see the light of our sun because all optical systems on our world evolved to take advantage of what we call the visible light spectrum. In fact, most of our sun's radiation is in the visible spectrum, so it only makes sense that our eyes evolved to detect this abundant radiation.

Answer 5

No, not a coincidence. Our sight evolved to recognize a portion of the electromagnetic spectrum that was abundant.
